I’ve just started HVE and I see a message telling me the “Application is Node Locked”. Then I see another message telling me “License file not found. Running in Demo Mode.” I have successfully used HVE on this computer before.

The “Application is Node Locked” message is telling you that the license manager is expecting to match the code in your license file with the code on your EDKEY. You need to check that your EDKEY is plugged in and is being recognized by your computer. You can select Help, Tech Support from HVE’s main menu to display the code for the EDKEY seen by the license manager.
